12 Claims. (Cl. 93.82)

Our invention relates to an improvement in a process for continuously wrapping ice cream or other products and its novelty consists in the steps of said process and the products produced thereby. 7

There is now on the market a paper tube forming and filling machine for wrapping ice cream or other products continuously, known as the Clarence W. Vogt machine and made under United States Patents Nos. 1,801,740, 1,801,863, 1,801,864 and 1,906,183 but it uses glue in securing the wrapper together. This is objectionable because it is unhygienic because the glue contaminates the material in the container and also because it either does not stay fastened with sufficient security if inadequately glued or is too difiicult to remove if glued too much.

Our process solves these problems and furnishes a new wrapper or container which is positively locked or fastened together so that the fastening is very strong against inside pressure but fragilewhen pulled apart on the outside as is desired in unwrapping the container.

Referring to the drawings Figure 1 is a. top plan view of our mechanism as it is attached in position on said patented Vogt paper tube forming and filling machine.

Figure 2 is a side elevation of the lifting mechanism of the upper shoe.

Figure 3 is a perspective of the complete paper tube or container made by our process and apparatus.

Figure 4 is a vertical cross sectional view on the line 4-4 of Figure 1.

Figure 5 is a horizontal cross sectional view of Figure 4 on the line 5--5.

In the drawings 6 is a hygienic ice cream or other material filling tube of said Vogt paper tube forming and filling machine rigidly mounted in a fixed position by means of the clamping bracket 1 of usual construction, which is rigidly secured at 8 to a floor or base 9 in the usual well known manner. An inner forming tube l0, also held rigidly in position by brackets l, is mounted over saidhygienic tube 6 with a very slight insulat'ing space of air between. A lower or bottom shoe l I constituting the outer lower half of an outer forming tube is held rigidly in a fixed position by means of supporting brackets l2 secured in the usual well known manner at l3 to the base or floor 9 so that it is immediately around the lower half of the inner forming tube H]. An upper shoe l4 completing the outer forming tube with the lower shoe l I is mounted thereon by means of arms l5 which terminate in plates It at one end which are rigidly secured at ll to the said upper shoe l4 and are pivoted by means of the usual bearings on shafts l8 in the heads of brackets I 9 rigidly secured at 20 in the well known manner to the plate or floor 9. These arms l5 5 are counterbalanced by adjustable weights 2| mounted thereon in the usual well known manner with set screws 22, so that said upper shoe H can be raised and lowered quickly and easily. The upper shoe I4 also has slotted ears 23 which are in alignment with similar ears 26 integral with the lower shoe l I and which carry clamping bolt members 25 with a spring member 26 under the ears 24 on said bolt so as to permit of an easy riding of said upper shoe M on said lower shoe l l as the paper tube being formed passes therethrough.

A pair of circular plates 21 having puncturing or piercing teeth 28 arranged around the entire outer periphery of said circular plates are mounted on shafts 29 so as to rotate freely thereon, and said shafts 29 are rigidly secured at 30 in the usual well known manner to the arms 3!, which in turn are pivoted at 32 in the usual manner on the posts 33 so as to turn freely thereon, and said arms 3| have handles 34 extending from the outer ends thereof so that said toothed plates 21 can be swung. out of engagement as desired. There are also limiting elements 35 rigidly secured at 36 to the plate or floor 9 so as to prevent the toothed plates 21 from swinging beyond the desired point for effecting the piercing of the paper tube and interlocking of the same. The teeth 28 have their highest point 31! in the rear portion of the tooth 28 as it rotates with the tubular container being formed in our device and the high point 31 runs down to a low point 38 at the iron of the tooth 28 as it rotates.

There is a, slot 39 out through the upper shoe l4 at the right side of Figure 4 as shown in the 40 drawings, and a narrow shearing slot 39' on the side of the inner'forming tube l0 for the teeth 28 of the plate 21 and a slot 40 on the left hand side of Figure 4 through the lower shoe II and' a narrow shearing slot 40' on the side of the inner s forming tube It for the clearance of the teeth 28 on the plate 21 on that side.

In operating our device as described inconjunction with the Vogt paper tube forming and filling machine, a strip of paper M will be run from the usual reel holding the same, not shown herein, over the innerforming tube Ill and the shoe l4 will be raised by means of the pivoted arms l5 so that said upper strip of paper 4| will be in position over said inner forming tube I0,

and an under strip of paper 42 will be drawn through over the under side of the inner forming tube I0 and under the lower outer shoe II, and as there are slots 43 and 44 the under strip of paper 42 will project through said continuous slot 43 to form a flange 45, and the upper strip of paper 4| will pass through the continuous slot 44 forming an outer flange 48. It will also be apparent that the upper strip of paper 4| overlaps the under strip of paper 42 at 4'! and that the under strip of paper 42 overlaps the upper strip of paper 4| at 48. These overlapping portions 41 and 48 are where we desire to secure the two strips of paper 4| and 42 together to form the cylindrical container or tube for holding the ice cream or other product to be filled thereinto.

The two strips of paper 4| and 42 are gripped by the usual Vogt conveyor (not shown) and pulled through the mechanism described in an absolute s ynchronism, thereby forming the continuous tubular paper tube or container for filling.

Our device locks and securely fastens together these two formed semi-tubular members 4| and 42 by means of the teeth 28 of the plates 21 which rotating in the same direction with the line of travel of said paper impinge upon said paper and pressing the same against the shearing edges of the slots 39 and 40 form a continuous series of punches or piercings through each side of the said overlapped portions 41 and 48 of the semitubulai' paper members 4| and 42, whereby the series of paper tabs 49 are projected inwardly and backwardly of the line of movement. I'hese inwardly projected tabs 49 are flattened down as the tube is drawn on over the inner forming tube As the tube thus formed and secured together is filled with ice cream at a point beyond the Figure 1 shown herein where the hygienic tube 6 ends within said paper tube, the ice cream or otherproduct Will fill said paper tube, and as the inwardly turned tabs 49 have been somewhat flattened down they will be further flattened down and the slight openings filled by ice cream or other product being filled into said paper tube.

As the continuous tubular container formed thus by the interlocking tabs 49 in the overlapping side edge portions of paper strips 4| and 42 is filled by ice cream or some other product, it is drawn on to a point where it is cut off in desired lengths and carried forward for further treatment as may be desired.

It will be particularly noted that the entirely novel container as shown in Figure 3 resulting from our process and apparatus has a continuous row of tabs 49 on each side projecting inwardly slightly and which, as the container is put under pressure from the inside, causes said interlocked tabs to merely pull sidewise, causing a binding of the projecting tabs on the sides of the double hole in the two strips 4| and 42, and that the strength of this interlocking in that direction is more than could be overcome by any intended use of said container for ice cream or other product.

However, if the two flanges 45 and 46 are taken between the flngers of each hand and pulled gently, the tabs 49 are easily and without resistance lifted up and out of the holes made by piercing strips 4| and 42 because of the direction of the pull or tension. Thus the novel container 50 formed by our process and apparatus completely solves the problem of a hygienic container having more than the recognized strength for holding the ice cream or other product perfectly for shipment and handling but being subject to quick and easy opening for use.

It will be apparent that a metal adaptable to the piercing and bending out of tabs may be used in our process instead of a paper-like material and that many variations may be made in our invention without departing from the spirit and intent of the same.
